Anton Webern (3 December 1883 – 15 September 1945) was an Austrian composer and conductor. He was a member of the Second Viennese School. As a student and significant follower of Arnold Schoenberg, he became one of the best-known exponents of the twelve-tone technique; in addition, his innovations regarding schematic organization of pitch, rhythm and dynamics were formative in the musical technique later known as total serialism.
Webern was not a prolific composer; just thirty-one of his compositions were published in his lifetime, and when Pierre Boulez oversaw a project to record all of his compositions, including those without opus numbers, the results fit on just six CDs. However, his influence on later composers, and particularly on the post-war avant garde, was immense. His mature works, using Arnold Schoenberg's twelve-tone technique, have a textural clarity and emotional coolness which greatly influenced composers such as Pierre Boulez, Luigi Nono, Karlheinz Stockhausen and Milton Babbitt.
Like almost every composer who had a career of any length, Webern's music changed over time. However, it is typified by very spartan textures, in which every note can be clearly heard; carefully chosen timbres, often resulting in very detailed instructions to the performers and use of extended instrumental techniques (flutter tonguing, col legno, and so on); wide-ranging melodic lines, often with leaps greater than an octave; and brevity: the Six Bagatelles for string quartet (1913), for instance, last about three minutes in total.
Webern's earliest works are in a late Romantic style. They were neither published nor performed in his lifetime, though they are sometimes performed today.
